An innocent plea has been entered for a man accused of killing his girlfriend in their Black River Falls apartment.

37-year-old Michael Harmon stood mute at his arraignment yesterday in Jackson County Circuit Court. A judge entered the plea to a charge of first-degree intentional homicide as a repeat offender. Harmon is accused of shooting 34-year-old Angela Nelson, who was found dead in their bathtub last June ninth. Harmon told police that he and Nelson were in a struggle when the gun went off, and his lawyer is claiming self-defense. But in previous testimony, a medical examiner said there was no way the victim was shot at close range, based on the area of the bullet wound. Authorities said Harmon left Black River Falls after the shooting, and was later arrested in Milwaukee -- where his father is a former police officer. No new court dates have been set in the case.
